IMPROVEMENT lN TRACTION-ENGINES.

Specification forming part of Letters Patent No. 127,143, dated May 28,1872.

Specification describing certain Improvements in Traction-Engines,invented by WM. C: B1BB, of Madison, Georgia.

Nature and Object.

The object of my invention is to furnish a power wagon which may bepropelled by steam, gas, or air, for general use, but more especiallyfor traction purposes 5 but may also be used as a stationary power forthrashing grain and other light work.

rIhe iirst part of my invention relates to the combination of a rotaryengine with a countershaft forpropelling a steam road-wagon, to be usedeither as such singly, or for traction purposes for the road, or plowingand reaping. The second part of my invention relates to the swivelconnecting the frame or body to the front axle, and so arranged as toallow the free movement of the axle in steering, and to provide foruneven roads. The third part of my invention relates to the use ofIndia-rub ber springs placed underneath the frame, both in front andrear, to relieve the concussion as the wagon passes over unevensurfaces.

Description of Drawing.

Figure 1 is a plan view of wagon. Fig. 2 is a side elevation. Fig. 3 isa front view.

A A are the engines. B B are the countershafts. O O C O are spur-wheelson countershafts. D D D D are spur-wheels attached to wagon-wheels E E EE, revolving on axles F F. G is the boiler. His the coal-box. I is thewatentank. J is the tool-box. K is the feed-pump. L is the steeringapparatus. M M are the steering-chains. N are bea-rings for support ofcountershaft. O O O are guttapercha springs. P is the pin to swivel onfront axle. Q is the brace for the front axle. S S is the frame forbody.

General Description.

S S is the frame suspended from front and rear axles, havinggutta-percha springs underneath and on the supports. G is the boiler,and is connected with the engines A A by pipes, through which the steamis conveyed. The pipe in front enters the front engine in the center ofits top, and is connected by either a flexible pipe or a universaljoint, to allow of its moving freely in steering, or when the wheelfalls in a rut. When the engines are made to revolve, the countershaftsrevolve with the1n,and the spur-wheels O O O O being carried around withthe countershaft, their teeth engage with the teeth of the largerspurwheels D D D D attached.' to the Wagonwheels E E E E, and causingthem to revolve the wagon is driven back or forward, as may be desired.

When it is desired to steer the wagon, the apparatus L is turned, andthe chains M M being attached to the axle, are wound up on one side andlet out on the other, so that the axle is moved steadily in the desireddirection, and moves freely on the swivel P.

I am aware that rotary engines have been applied to railroadlocomotives; but

What I claim, and ask that Letters Patent may be granted to me for, is-

The combination of rotary steam-engines, attached to the front and rearcountershaft, connected with the boiler by means of tubes, substantiallyas and for the purpose hereinbefore set forth.
